VNC black screen of sadness

Did you connect to your VNC server only to be greeted by a black screen of sadness? 

It happened to me not long ago and I don't know what made me try this, but here's what fixed it:

$ vncpasswd

As always, you're welcome.

Old code, new Xcode

When you download some old code from the Interwebs with such like:

[self.window addSubview:self.viewController.view];

and it runs just fine... and later you update Xcode and start getting runtime errors:

Applications are expected to have a root view controller at the end of application launch

Fortunately the fix is easy:

[self.window setRootViewController:self.viewController];

Thanks, Interwebs!!

They cost me all of my diamonds, but I think it was worth it!

Major accomplishment

I did it!! I beat the Cheshire Cat in Yahtzee Buddies!! 

The dice are cool and all, but pretty hard to read...

I'll stick to my favorite bronze dice.

Beach Ball!!!

I finally got my beach ball dice! Yes, I had to beat 25 different opponents in 24 hours, but it was totally worth it, right? Right? 

But here's the thing. There's a bug - at least on iOS - where the progress of your wins against different opponents isn't getting updated. So if you want to earn the beach ball dice, KEEP A LIST OF THE PLAYERS YOU BEAT (and when) and then paste that information into a help request so customer service can give you credit for your achievement, as they did do for me. Thanks, Yahtzee! 

Now here's my whole lineup of dice. I do expect this will be my final update, since the remaining locked dice involve tournaments and dice masters that are impossible to beat without spending moneys on bonus rolls. C'est la vie!

My dice. Don't judge me. :-)

Swift selector argument - yes you can!

Selectors are an Objective C thing, but sometimes you have to use them in Swift.

For example, if you are calling performSelectorOnMainThread to work around the problem between GCD and UIWebView that causes hangs in stringByEvaluatingJavaScriptFromString (see <a href="">here</a>) you don't have a choice.

But how to pass an argument? I defined my selector function to take AnyObject? just as I assumed I should since withObject:AnyObject?

So tl;dr - here's what I was doing wrong. The colon at the end of the selector DOES MATTER. Well duh, of course it does, because it indicates there's an argument. Here's an example of everything working correctly...

  private func caller() {
    let arg = 42
    performSelectorOnMainThread("myfunc:", withObject: arg, waitUntilDone: false)

  func myfunc(arg: AnyObject?) {
    guard let n = arg as? Int else {
      print("how did we get in this cornfield?")
    print("and here we are with our arg n: \(n)")

...and the proof of the pudding - my, how tasty!

and here we are with our arg n: 42

I hope this saves somebody else a few hours of struggle!
